pihole v6 support - unknown long flag '--pihole-api-version'

[alexanderccc]

What happened:
Upgraded both external-dns and pi-hole to move to the v6 version of pi-hole. external-dns fails to start due to

flag parsing error: unknown long flag '--pihole-api-version'

What you expected to happen:
external-dns to start successfully and function with the updated pihole API

How to reproduce it (as minimally and precisely as possible):
try to start this container registry.k8s.io/external-dns/external-dns:v0.16.1 with the --pihole-api-version="6" argument (as described in the docs).

Anything else we need to know?:
Might be build related, going through the implementation issue (#5226), one of the staging images
gcr.io/k8s-staging-external-dns/external-dns:v20250402-v0.16.1-48-g1efdf416 works as expected

Environment:

• External-DNS version (use external-dns --version): 0.16.1
• DNS provider: pihole
• Others: v6 api

Hi, facing same issue here.

[ivankatliarchuk]

Could someone please point me to the release notes that explicitly state the release of Pi-hole v6 support?

[alexanderccc]

Right... Sorry for that, I just noticed it wasn't released and it's just part of the master branch docs, will wait for the next release, hopefully soon 🤞
